- 28 bones of the skull
- How many bones form the cranium?
- 8 cranial bones
- What is the frontal bone?
- it forms the front part of the skull above the eyes, which includes the forehead and part of the nasal cavity.
- What is the parietal bone?
- The 2 parietal are located behind the frontal bone. These bones form the greater part of the right and left sides and the roof of the skull.
- What are the temporal bones?
- The temporal bones form the sides and part of the base of the skull in the area of the ear.
- What is the occipital bone?
- The occipital bone forms the back part of the skull and the base of the cranium.
- What is the sphenoid bone?
- The sphenoid bone has a wing-like shape and is internally wedged between several other bones in the front part of the cranium.
- What is the ethmoid bone?
- The ethmoid bone is situated in front of the sphenoid bone in the front part of the cranium.
- How many bones of the face are there?
- The facial skeleton consists of 14 staionary bones and a mobile lower jawbone.
- What are the manillae bones?
- The maxillae bones are the largest bones of the face and together form the upper jaw.
- What are the palatine bones?
-
The palatine bones are located behing the maxillae.
Somewhat "L" shaped and form the posterior portion of the hard palate and the floor of the nose. - What are the Zygomatic Bones?
-
-Zypoma, Malar Bones
The zygomatic bones make up the prominence of the cheeks and extend from the zygomatic process of the temporal bones to the zygomatice process of the maxilla. "cheek bones" - What are the Lacrimal Bones?
-
The lacrimal bones are the smallest and most fragile of the cranial bones.
The are located in back of the frontal process of the maxilla. - What are the nasal bones?
-
The nasal bones are small oblong bones.
they lie side by side and are fused at the midline to form the bridge of the nose (nasal septum).
-responsible for the shape of the nose. - What is the inferior nasal conchae?
-
The inferior nasal conchae are curved, fragile, scroll-shaped bones that lie in the lateral walls of the nasal cavity.
-prived support for mucous membranes within the nasal cavity. - What is the vomer bone?
-
The vomer bone is a thin, flat, single bone almost trapezoid in shape.
It connects the ethmoid bone and together they form the nasal septum. - What is the Mandible?
- The mandible (lower jaw) is the longest, strongest, and the only movable bone in the skull.
- What is the Mandible Condyloid process?
-
Also called mandibular condyle, located posterior on the ramus and forms the head of the mandible.
It is knuckle-shaped, and articulates in the glenoid fossa of the temporal bone to form the temporal mandibular joint. - What is the Mandible Coronoid process?
- Located anterior of the condyle, and provides attachment for the temporal's muscle, which helps left the mandible to close the mouth.
- What is the Mandible alveolar process?
- Supports the teeth and the mandibular arch.
- What is the Mandible mental protuberance?
- Also reffered to as the chin and is located at the midline of the madible.
- What is the Mandible Metal Foramen?
-
Located on the facial surfaces of the mandidle on the both the right and left sides, just below the second premolars.
This opening contains the mental nerves and blood vessels. - What is the Mandible Body?
- The heavy, horizontal portion of the mandible below the mental foramen extending from the angle to the parasyplysis region.
- What is the Mandible Angle?
- Junture wher the body of the mandible meets with the ramus.
- What is the Mandibular foramen?
-
Located near the center of each ramus on the medial side (inside), through this opening passes blood vessels and the interior alveolus nerve, which supplies the roots of the mandibular teeth.
-injection site. - What is the Glenoid Fossa?
- Oval depression in the temporal bone that articulates with the mandibular condyle.
- What is the Articular eminence?
- Ramp-shaped segment of the temporal bone located anterior to the glenoid fossa.
- What is the Condyle?
-
The knucle shaped portion of the mandibular ramus found on the end of the condyloid process.
-hinge join of the TMJ - Orcbicularis oris.
-
Located between the slin and the mucous membranes of the lips.
Makes lips close and pucker. - Buccinator.
- Located in the walls of the cheeks, holds food in contact with teeth when chewong, and assists in blowing air out of the mouth.
- Mentalis.
- Raises and wrinkles the skin of the chin and decreases and proturudes the lower lip.
- Zygomaticus Major.
- Riases the corner of mouth when smiling.
- Masseter.
- Closes jaw; flat, thick muscle.
- Temporalis.
- Closes the jaw; fan shaped
- Medial pterygoid.
- Closes the jaw; parallels masseter muscle.
- Lateral pterygoid.
- Opens the jaw; allows grinding action side to side, and protrudes the mandible.
- Where is the Sublingual Salivary gland?
-
One each side underneath the tongue, in the floor of the mouth.
-smallest of the glands, secretes, thick stringy mucous. - Where is the Submandibular Salivary gland?
-
Posterior portion of mandible, lingual to mandibular incisors.
-walnut sized. Secretes watery fluid with some mucous. - Where is the Partoid Salivary gland?
-
Inside cheek, opposite maxillary 2nd molar.
-Largest gland, secretes clear watery fluid.
